SMB1SigningDigest

public SMB1SigningDigest(byte[] macSigningKey)

This constructor used to instance a SigningDigest object for signing/verifying SMB using kerberos session key. The MAC Key = concat(Session Key, Digest of Challenge); Because of Kerberos Authentication don't have challenge, The MAC Key = Session Key

パラメータ:

macSigningKey - The MAC key used to sign or verify SMB.

SMB1SigningDigest

public SMB1SigningDigest(byte[] macSigningKey,
                         int initialSequence)

Construct a digest with a non-zero starting sequence number

パラメータ:

macSigningKey -

initialSequence -

public SMB1SigningDigest(SmbTransportInternal transport,
                         NtlmPasswordAuthenticator auth)
                  throws SmbException

パラメータ:

transport -

auth -

例外:

SmbException

メソッドの詳細

update

public void update(byte[] input,
                   int offset,
                   int len)

Update digest with data

パラメータ:

input -

offset -

len -

digest

public byte[] digest()

戻り値:

calculated digest

sign

public void sign(byte[] data,
                 int offset,
                 int length,
                 CommonServerMessageBlock request,
                 CommonServerMessageBlock response)

Performs MAC signing of the SMB. This is done as follows. The signature field of the SMB is overwritten with the sequence number; The MD5 digest of the MAC signing key + the entire SMB is taken; The first 8 bytes of this are placed in the signature field.

定義:

sign インタフェース内 SMBSigningDigest

パラメータ:

data - The data.

offset - The starting offset at which the SMB header begins.

length - The length of the SMB data starting at offset.

request - request message

response - response message

verify

public boolean verify(byte[] data,
                      int offset,
                      int l,
                      int extraPad,
                      CommonServerMessageBlock m)

Performs MAC signature verification. This calculates the signature of the SMB and compares it to the signature field on the SMB itself.

定義:

verify インタフェース内 SMBSigningDigest

パラメータ:

data - The data.

offset - The starting offset at which the SMB header begins.

extraPad - extra padding to include in signature

m - The message to verify

戻り値:

whether verification was unsuccessful
